The Checkered Setwing was found for the first time in Maricopa Co. in 2013 and until now, was not known to occur at any other county location.

An individual of this species was tentatively identified by D. Elefante at Papago Park (Phoenix, Maricopa Co.) in mid-July 2014. The (presumably same) individual was relocated at the same site on 21 July, providing the second record for this species in Maricopa Co. and the first for the Phoenix Metro area.
